Head gasket install questions

[blackbox]

Hey guys i found out that i had blown head gaskets. A friend of mine told me to get stock replacement gaskets. Will these hold at 21 psi boost 400 rwhp. The heads are stock and i was also woundering is there any way to install arp studs without pulling the motor. The heater box is also still on the the car so it is tight in that area. If no will arp 12 pt head bolts be ok for my combination right now.

i was just told that i could install head studs with motor still in place with the new arp studs with a allen key on the top. I was woundering who sells these, also what is best 12pt or 6pt head studs.

you can get the head studs from almost every vendor on this board. As far as head gaskets everyone has there own way of doing things. Stocks will work and So Will RJC and there are others as well its all about what you want to do.
